Description

Technical Field

[0001] The utility model relates to the field of cartons, in particular to an easy-to-tear carton. Background Art

[0002] Corrugated boxes are the most widely used packaging and transportation containers today. With the development of commerce, most cartons have become disposable consumables. After the express delivery is unpacked, the cartons become waste and are recycled.

[0003] Since express delivery boxes are mostly sealed with tape, people need to use tools like knives and scissors to open them. These tools are not always readily available, causing considerable trouble and inconvenience. In recent years, to improve the user experience of unpacking packages, zipper-type easy-tear cartons have emerged, which are widely used in the express delivery industry. These cartons use built-in plastic strips to break the carton, allowing for quick opening. However, these cartons are expensive to produce. In today's low-profit environment, most businesses still choose traditional cartons over zipper-type easy-tear cartons. However, these traditional cartons do not improve the user experience of unpacking packages. Furthermore, because zipper-type easy-tear cartons use higher-strength corrugated paper, they use more paper and glue than standard cartons, which is also environmentally friendly.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0005] The purpose of the utility model is to provide an easy-tear carton, aiming to solve the problem that the existing traditional cartons are inconvenient to disassemble and have a poor user experience, and to replace the existing zipper-type easy-tear carton with a higher cost.

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer and more specific, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments and implementation methods derived by ordinary technicians in this field without departing from the concept of the present invention and without making creative efforts by adopting the same or similar technical features shall fall within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that unless otherwise specified, the term "easy-to-tear unit area" should be understood in a broad sense, referring to an area that can be used to implement the functions of the present invention. The tape area of the carton and / or the surrounding area of the tape area can serve as the easy-to-tear unit area.

[0036] In the description of the present invention, it should be noted that the terms "upper end", "lower end", "front end", "two ends", "side", "lower side", "upper side", "both sides", "edge", "back", "up", "down", "bottom", "surrounding", "one end", "one side", "front", "the other side", "outside", "left and right", "vertical", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and therefore cannot be understood as limiting the present invention.

[0037] Implementation Case 1

[0038] like Figure 1 As shown, after the corrugated cardboard is folded into a carton box 10, the carton is sealed with tape 30, and the side with one end of the tape is considered the front. The easy-tear unit area on the front of the box 10 is provided with a release coating 20, which can be made of silicone oil and has low adhesion properties. Figure 1 When the carton is sealed with tape 30, it covers most of the release coating 20. Similarly, a release coating can also be applied to the other side of the tape (not shown). When packaging items, the corrugated cardboard is folded into the carton body 10. After the items are loaded, the top cover is closed. Then, tape 30 is applied to the carton body 10. The end of the tape 30 covers most of the release coating 20, leaving a small area uncovered. The corrugated cardboard is die-cut, creased, and stapled or glued to form a corrugated box. As a semi-finished product, the carton already has creases and shapes. During production, release coating 20 is simply applied to the pre-designed easy-to-tear areas of the semi-finished carton.

[0039] like Figure 2 When disassembling the box, you only need to use your fingernail to scratch the edge of the tape 30 at the release coating 20, which makes it easier to separate the edge of the tape 30 from the box 10. In this way, you can tear open the carton by holding one end of the tape with your hand.

[0040] Figure 1 The release coating 20 can also be changed to an isolation adhesive layer, which is an adhesive release paper or an adhesive release film. This adhesive release paper or adhesive release film has a pressure-sensitive adhesive on one side adhered to the easy-to-tear unit area, and the other side has a release coating with low adhesion. The method of use is the same as above.

[0041] A reminder slogan or reminder mark (not shown in the figure) can also be set in the easy-to-tear unit area to make people easily notice that the paper can be torn open.

[0042] Implementation Case 2

[0043] like Figure 4As shown, the easy-tear unit area on the front of the box body 10 is provided with an adhesive barrier layer. The adhesive barrier layer is made of a T-shaped adhesive plastic film 26. The upper end of one side of the T-shaped adhesive plastic film 26 is provided with a pressure-sensitive adhesive (not shown), while the lower end is free of pressure-sensitive adhesive. The end of the adhesive tape 30 is adhered to most of the T-shaped adhesive plastic film 26, but a small portion of the lower end of the T-shaped adhesive plastic film 26 is not covered by the adhesive tape 30. Similarly, the other side of the T-shaped adhesive plastic film 26 (not shown) can also be provided with a T-shaped adhesive plastic film 26.

[0044] like Figure 5 As shown, it is a cross-section of the box body. A sticky plastic film 26 is provided in the easy-tear unit area on one side of the box body 10. One side of the sticky plastic film 26 is partially covered with a pressure-sensitive adhesive 25 and is attached to the box body 10. A tape 30 is attached to the box body 10 and the other side of the sticky plastic film 26. The tape 30 only sticks to most of the upper end of the sticky plastic film 26. A small part of the lower end of the sticky plastic film 26 without the pressure-sensitive adhesive is exposed outside the coverage of the tape 30.

[0045] like Figure 6 The figure shows the structure of the adhesive plastic film 26 being separated from the box body at its edge. The easy-tear unit area on the front of the box body 10 is provided with an adhesive barrier layer, which is a T-shaped adhesive plastic film 26. When opening the box, use your fingers to pull at the lower end of the T-shaped adhesive plastic film 26 to separate the edge of the tape 30 from the box body 10. Then, use your fingers to grasp the edge of the adhesive plastic film 26 and the edge of the tape 30 to tear the tape 30.

[0046] Similarly, the adhesive plastic film 26 at the easy-to-tear unit area can also be replaced by an adhesive paper with relatively higher toughness, and the principle and method of use are the same as above.

[0047] Implementation Case 3

[0048] like Figure 7As shown, after the corrugated cardboard is folded into a carton body and filled with items, the carton is sealed with tape 30, and the side with the tape end is considered the front. The easy-tear unit area on the front of the box body 10 is provided with an easy-tear mark 21. The easy-tear mark 21 is U-shaped and consists of a dotted line mark 23 and a knife cut mark 22. When the carton is a semi-finished product, it has an indentation and shape. During production, it is only necessary to set the U-shaped easy-tear mark 21 in the planned easy-tear unit area of the semi-finished carton. The depth of the easy-tear mark 21 can be cut into the middle layer of the corrugated cardboard, or cut into the surface layer. Similarly, the other side with the tape end can also be provided with a U-shaped easy-tear mark 21 (not shown). When packing items, the corrugated cardboard is folded into a carton box 10, the items are loaded and the upper cover of the box is closed, and then the box 10 is adhered with tape 30, and the end of the tape 30 is located at the U-shaped upper part of the U-shaped easy tear mark 21.

[0049] like Figure 10 , which is a schematic diagram of a portion of the front of box 10. Box 10 is made of corrugated cardboard. Knife cuts 22 leave cuts in the outer layer of corrugated cardboard. Using a fingernail to scratch at these cuts 22 easily separates the outer layer from the middle layer, leaving a raised edge. Grasping the raised edge with a fingernail allows the outer layer to be torn along the dotted line 23. When box 10 is taped shut, the outer layer is taped, allowing it to be torn along with the tape.

[0050] The knife cut 22 can be cut deeper and can cut into the middle layer of corrugated cardboard. In this way, you can press along the lower side of the knife cut 22 with your fingernail, which makes it easy to make the surface paper on both sides of the knife cut 22 have a gap, making it more convenient to use your fingernail to pick out the surface paper at the knife cut 22.

[0051] The knife cut mark 22 can also be provided with a groove mark, such as Figure 11 This is a schematic diagram of a portion of the front of the box 10, with a tool used to cut out knife marks and press out groove marks. The groove marks are located below the knife marks and next to the knife marks. In this way, there is a gap between the surface paper on both sides of the groove mark 27, which makes it convenient to use fingernails to pick the surface paper of the corrugated paper. Figure 12 It is a schematic cross-sectional view of the corrugated cardboard on the front side of the box body 10. The groove marks 27 form grooves on the corrugated cardboard to facilitate fingernails to pick at the surface paper of the corrugated cardboard.

[0052] like Figure 13 , is a schematic diagram of a portion of the front of the box body 10. In order to make it easier to remove the corrugated cardboard cover paper, you can also use a blade to bevel the cover paper on the upper side of the groove mark 27 at a smaller angle in the plane direction of the corrugated cardboard. In this way, the edge of the cover paper on the upper side of the groove mark 27 is separated from the middle layer of paper, making it easier to use your fingernails to remove the cover paper at the groove mark 27. Figure 14, is a schematic cross-sectional view of the corrugated cardboard on the front of the box body 10. The outer skin paper on the upper side of the groove mark 27 is beveled with a blade so that the edge of the outer skin paper is separated from the middle layer of paper.

[0053] In addition to being set before the carton is finished, the U-shaped tear mark 21 can also be set in the tear unit area with a tool after the carton body is loaded with items, the cover is covered and the carton body is sealed with tape.

[0054] Since the easy tear mark 21 is relatively thin, people may not notice the easy tear mark 21. A reminder slogan or reminder mark (not shown in the figure) can be set in the easy tear unit area to make people easily notice that it can be torn.

[0055] Implementation Case 4

[0056] like Figure 8 As shown, after the corrugated cardboard is folded into a carton body and the items are loaded, the carton is sealed with tape 30, and the side with one end of the tape is considered the front. The easy-tear unit area on the front of the box body 10 is provided with an easy-tear mark 21, and the easy-tear mark 21 is in the shape of a straight line. The straight-shaped easy-tear mark 21 is composed of a dotted line mark 23 and a knife cut mark 22. The knife cut mark 22 is located in the middle, and the dotted line marks 23 are located on both sides of the knife cut mark 22. Similarly, a straight-shaped easy-tear mark 21 can also be provided on the other side with one end of the tape (not shown in the figure). When the carton is a semi-finished product, it has an indentation and shape. During production, it is only necessary to set the straight-shaped easy-tear mark 21 in the planned easy-tear unit area of the semi-finished carton. The depth of the easy-tear mark 21 is to cut to the middle layer of the corrugated cardboard, or to cut to the surface layer. When packaging items, the corrugated cardboard is folded into a carton box 10 , and after the items are loaded, the upper cover of the box is closed, and then the box 10 is adhered with tape 30 , with the end of the tape 30 located above the tear mark 21 .

[0057] In addition to being set before the carton is finished, the straight tear mark 21 can also be set in the easy-tear unit area with a tool after the carton body is loaded with items, the cover is covered and the carton body is sealed with tape.

[0058] When unpacking, the cut mark 22 can be scratched with a fingernail to lift the corrugated cardboard cover of the box body 10, and then the lifted corrugated cardboard cover can be grasped with a fingernail and torn off together with the adhesive tape 30. The cut mark 22 can be cut deeper, so that the middle layer of the corrugated cardboard can be cut. In this way, the fingernail can be pressed along the lower side of the cut mark 22 to easily create a gap between the cover papers on both sides of the cut mark 22, making it easier to use the fingernail to scratch the cover paper at the cut mark 22.

[0059] Since the easy tear mark 21 is relatively thin, people may not notice the easy tear mark 21. A reminder slogan or reminder mark (not shown in the figure) can be set in the easy tear unit area to make people easily notice that it can be torn.

[0060] Implementation Case 5

[0061] like Figure 9 As shown, after the corrugated cardboard is folded into a carton body and filled with items, the carton is sealed with tape 30, and the side with one end of the tape attached is considered the front. The easy-tear unit area on the front of the box body 10 is provided with an L-shaped easy-tear mark 21. The easy-tear mark 21 is L-shaped, and two mirror-image L-shaped easy-tear marks are located at the two corners of the end of the tape 30. The L-shaped easy-tear mark 21 consists of a dotted line mark 23 and a knife-cut mark 22. Similarly, two mirror-image L-shaped easy-tear marks can also be provided on the other side with one end of the tape attached (not shown). When the carton is a semi-finished product, it has an indentation and shape. During production, only the L-shaped easy-tear mark 21 needs to be set in the planned easy-tear unit area of the semi-finished carton. The depth of the easy-tear mark 21 can be cut into the middle layer of the corrugated cardboard, or cut into the surface layer. When packaging items, the corrugated cardboard is folded into a carton body 10. After the items are loaded, the top cover of the carton body is closed. Then, the carton body 10 is affixed with adhesive tape 30. The end of the adhesive tape 30 is located in the area formed between the two mirror-image L-shaped tear marks. In addition to setting the L-shaped tear mark before the carton is completed, it can also be set in the tear unit area using a tool after the carton body is loaded with items, the cover is closed, and the carton body is sealed with adhesive tape.

[0062] When unpacking, you can use your fingernail to scratch the knife cut 22, so that the corrugated cardboard surface paper of the box body 10 is tilted up, and then use your fingers to pick up the tilted corrugated cardboard surface paper and tear it off together with the tape 30. You can also use your fingernail to press along the lower side of the knife cut 22 to make the surface paper on both sides of the knife cut 22 have a gap, which makes it easier to use your fingernail to scratch the surface paper at the knife cut 22, and then tear it off together with the tape 30.

[0063] Since the easy tear mark 21 is relatively thin, people may not notice the easy tear mark 21. A reminder slogan or reminder mark (not shown in the figure) can be set in the easy tear unit area to make people easily notice that it can be torn.

[0064] Implementation Case 6

[0065] like Figure 3As shown, after the corrugated cardboard is folded into a carton body and loaded with items, the carton is sealed with tape 30. The side with the tape end attached is considered the front. The easy-tear unit area on the front of the carton body 10 is provided with an X-shaped easy-tear mark 21, consisting of two knife cuts. The carton already has an indentation and shape when it is a semi-finished product. During production, the easy-tear mark 21 only needs to be provided in the planned easy-tear unit area of the semi-finished carton. The depth of the easy-tear mark 21 can be cut into the middle layer of the corrugated cardboard, or even into the surface layer. Similarly, the other side with the tape end attached can also be provided with an X-shaped easy-tear mark 21 (not shown). When packaging items, the corrugated cardboard is folded into the carton body 10, loaded with items, and the top cover is closed. The carton body 10 is then secured with tape 30, with the end of the tape 30 located above the X-shaped easy-tear mark 21.

[0066] When unpacking, use your fingernail to scrape the top paper at the upper corner where the two cuts intersect, causing the corrugated cardboard top paper of the box body 10 to tilt up. Then, use your fingers to grasp the tilted corrugated cardboard top paper and tear it off along with the tape. Of course, the cut can be made deeper, reaching the middle layer of the corrugated cardboard. This allows you to press the top paper at the angles to the left and right of the X-shaped easy-tear mark 21 with your fingernail, creating a gap between the top paper and the angles above and below the X-shaped easy-tear mark 21. This makes it easier to scrape the top paper at the cut with your fingernail. Because the easy-tear mark 21 is relatively thin, people may not notice it. A warning sign or indicator (not shown) can also be placed in the easy-tear area to easily remind people that it is possible to tear.

[0067] In addition to manually pressing the cover paper at the left and right corners of the X-shaped easy tear mark 21 with your fingernails, you can also use a tool to press the cover paper at the left and right corners of the X-shaped easy tear mark 21 in advance during production to create a certain height difference with the cover paper at the upper and lower corners of the X-shaped easy tear mark 21. To make it easier to remove the cover paper from the corrugated cardboard, you can also use a blade to bevel the cover paper at the upper corner at a small angle in the plane of the corrugated cardboard. In this way, the edge of the cover paper at the upper corner of the corrugated cardboard is separated from the middle layer of paper, making it easier to remove the cover paper at the upper corner with your fingernails.

[0068] Implementation Case 7

[0069] like Figure 15As shown, after the corrugated cardboard is folded into a carton body and filled with items, the carton is sealed with tape 30. The side with the tape end attached is considered the front. The easy-tear unit area on the front of the box body 10 is provided with an easy-tear mark 21 and a film 50. The easy-tear mark 21 is X-shaped and consists of two knife-cut marks. The film 50 has adhesive on one side. After the film 50 is applied to the easy-tear unit area, a tool is used to cut the X-shaped easy-tear mark 21 into the corrugated cardboard with the film 50. Similarly, the other side with the tape end attached can also be provided with an easy-tear mark 21 and film 50 (not shown). The carton already has an indentation and shape when it is a semi-finished product. During production, the easy-tear mark 21 and film 50 only need to be installed in the planned easy-tear unit area of the semi-finished carton. The easy-tear mark 21 can be cut deep enough to reach the middle layer or the surface layer of the corrugated cardboard. When packing items, the corrugated cardboard is folded into a carton box 10, the items are loaded and the upper cover of the box is closed, and then the box 10 is adhered with tape 30, and the end of the tape 30 is located in the area where the film 50 is attached on the upper side of the X-shaped tear mark 21.

[0070] When unpacking, you can use your fingernail to scratch the top paper at the upper corner where the two knife cuts intersect, causing the corrugated cardboard top paper of the box body 10 to tilt up. Then, use your fingers to pinch the tilted corrugated cardboard top paper and tear it off together with the tape. Due to the uneven quality of corrugated cardboard boxes, the top paper of some low-quality boxes is not easy to tear off in large pieces. However, after applying the film 50, under the action of the film, you only need to pinch a corner of the top paper to easily tear off the film 50, thereby tearing off the tape 30 stuck to the film 50. In addition to using the film 50, you can also use a tough sticker. Alternatively, you can cover the easy-to-tear unit area with a layer of film, or apply a coating layer to the easy-to-tear unit area. This can also achieve the same effect.

[0071] Of course, the cut can be made deeper, even into the middle layer of corrugated cardboard. This allows the user to press down on the outer layers of paper at the left and right angles of the X-shaped easy-tear mark 21 with a fingernail, creating a gap between the outer layers of paper at the upper and lower angles of the X-shaped easy-tear mark 21. This makes it easier to remove the outer layers of paper at the cut with a fingernail. Because the easy-tear mark 21 is relatively thin, people may not notice it. A warning sign or indicator (not shown) can be placed in the easy-tear area to easily indicate that the paper can be torn.

[0072] Of course, the knife cut 22 can be cut deeper, and can cut into the middle layer of corrugated paper. In this way, you can press it with your fingernail along the lower side of the knife cut 22, which makes it easy to make the epidermis paper on both sides of the knife cut 22 have a gap, making it more convenient to use your fingernail to pick out the epidermis paper at the knife cut 22.

[0073] The knife cut mark 22 can also be provided with a groove mark, reference Figure 11 and Figure 12 In this implementation example, a tool is used to cut the cuts and press the grooves. The grooves are located below and adjacent to the cuts. This creates a gap between the outer layers of the corrugated paper on either side of the grooves, making it easier to remove the outer layers with your fingernails.

[0074] In order to make it easier to remove the corrugated cardboard surface paper, you can also use a blade to bevel the surface paper on the upper side of the groove mark at a smaller angle in the plane direction of the corrugated cardboard. Figure 13 and Figure 14 In this way, the edge of the surface paper of the corrugated cardboard on the upper side of the groove is separated from the middle layer of paper, making it more convenient to use fingernails to pick out the surface paper at the groove.

[0075] Since the easy tear mark 21 is relatively thin, people may not notice the easy tear mark 21. A reminder slogan or reminder mark (not shown in the figure) can be set in the easy tear unit area to make people easily notice that it can be torn.

[0076] Implementation Case 8

[0077] like Figure 16 As shown, after the corrugated cardboard is folded into a carton body and the items are loaded, the carton is sealed with tape 30, and the side with one end of the tape is considered the front. The easy-tear unit area on the front of the box body 10 is provided with an easy-tear mark 21. The easy-tear mark 21 is H-shaped, and the HH-shaped easy-tear mark 21 consists of a dotted line mark 23 and a knife cut mark 22. The knife cut mark 22 is located in the middle, and two vertical dotted line marks 23 are located on both sides of the knife cut mark 22. The easy-tear mark 21 is set with a tool after the box body 10 is loaded with items and sealed with tape. The depth of the easy-tear mark 21 is to cut to the middle layer of the corrugated cardboard, or to the surface layer. With the development of science and technology and the enhancement of environmental awareness, the tape 30 can also use environmentally friendly tape to replace traditional tape, such as biodegradable tape.

[0078] When unpacking, the cut mark 22 can be scratched with a fingernail to lift the corrugated cardboard cover of the box body 10, and then the lifted corrugated cardboard cover can be grasped with a fingernail and torn off together with the adhesive tape 30. The cut mark 22 can be cut deeper, so that the middle layer of the corrugated cardboard can be cut. In this way, the fingernail can be pressed along the lower side of the cut mark 22 to easily create a gap between the cover papers on both sides of the cut mark 22, making it easier to use the fingernail to scratch the cover paper at the cut mark 22.

[0079] The knife cut mark 22 can also be provided with a groove mark, reference Figure 11 and Figure 12In this implementation example, after taping the box, a tool is used to cut and press the cuts. The grooves are located below and adjacent to the cuts. This creates a gap between the surface paper on either side of the grooves, making it easier to remove the surface paper with a fingernail.

[0080] In order to make it easier to remove the corrugated cardboard surface paper, you can also use a blade to bevel the surface paper on the upper side of the groove mark at a smaller angle in the plane direction of the corrugated cardboard. Figure 13 and Figure 14 In this way, the edge of the surface paper of the corrugated cardboard on the upper side of the groove is separated from the middle layer of paper, making it easier to use fingernails to pick out the surface paper at the groove.

[0081] Since the easy tear mark 21 is relatively thin, people may not notice the easy tear mark 21. A reminder slogan or reminder mark (not shown in the figure) can be set in the easy tear unit area to make people easily notice that it can be torn.

[0082] Some businesses will wrap the tape around the box or wrap another layer of tape perpendicular to the tape when packing and sealing the box. This implementation case also applies to such situations.

[0083] Implementation Case 9

[0084] like Figure 17 As shown, after the corrugated cardboard is folded into a carton body and the items are loaded, the carton is sealed with tape 30, and the side with one end of the tape attached is considered the front. The easy-tear unit area on the front of the box body 10 is provided with an easy-tear mark 21, which is a straight-line knife cut. The straight-line knife cut cuts horizontally through the end of the tape 30. Similarly, a straight-line knife cut can also be provided on the other side with one end of the tape attached (not shown in the figure). The easy-tear mark 21 is set with a tool after the box body 10 is loaded with items and sealed with tape. The depth of the easy-tear mark 21 can be cut to the middle layer of the corrugated cardboard, or to the surface layer. With the development of science and technology and the enhancement of environmental awareness, the tape 30 can also use environmentally friendly tapes instead of traditional tapes, such as biodegradable tapes.

[0085] When unpacking, you can use your fingernail to scratch the cut mark to make the corrugated cardboard cover paper of the box body 10 tilt up, then use your fingers to pick up the tilted corrugated cardboard cover paper and tear it off together with the tape 30. The cut mark can be cut deeper, so that the middle layer of the corrugated cardboard can be cut. In this way, you can press along the lower side of the cut mark with your fingernail to easily make the cover paper on both sides of the cut mark have a difference, making it easier to use your fingernail to scratch the cover paper at the cut mark.

[0086] The knife cuts can also be provided with grooves, see Figure 11 and Figure 12In this implementation example, after taping the box, a tool is used to cut and press the cuts. The grooves are located below and adjacent to the cuts. This creates a gap between the surface paper on either side of the grooves, making it easier to remove the surface paper with a fingernail.

[0087] In order to make it easier to remove the corrugated cardboard surface paper, you can also use a blade to bevel the surface paper on the upper side of the groove mark at a smaller angle in the plane direction of the corrugated cardboard. Figure 13 and Figure 14 In this way, the edge of the surface paper of the corrugated cardboard on the upper side of the groove is separated from the middle layer of paper, making it easier to use fingernails to pick out the surface paper at the groove.

[0088] Since the easy tear mark 21 is relatively thin, people may not notice the easy tear mark 21. A reminder slogan or reminder mark (not shown in the figure) can be set in the easy tear unit area to make people easily notice that it can be torn.

[0089] Some businesses will wrap the tape around the box or wrap another layer of tape perpendicular to the tape when packing and sealing the box. This implementation case also applies to such situations.

[0090] Implementation Case 10

[0091] like Figure 18 As shown, after the corrugated cardboard is folded into a cardboard box and filled with items, the box is sealed with tape 30, with one side considered the front. The tape 30 wraps around the box 10 in both the front and side directions. The front easy-tear unit area of the box 10 is provided with an X-shaped easy-tear mark 21, which is composed of two knife cuts that cut diagonally through the tape 30 to form the X-shape. Similarly, an X-shaped easy-tear mark 21 can also be provided on the back (not shown). The side easy-tear unit area of the box 10 is provided with a V-shaped easy-tear mark 21, which is composed of two knife cuts that cut diagonally through the tape 30 to form the V-shape. The easy-tear mark 21 is applied using a tool after the box 10 is filled with items and sealed with tape. The depth of the easy tear mark 21 is to cut into the middle layer of the corrugated paperboard, or to cut into the surface layer. With the development of science and technology and the enhancement of environmental awareness, the tape 30 can also use environmentally friendly tape to replace traditional tape, such as biodegradable tape.

[0092] When unpacking, you can use your fingernail to scratch the top paper at the upper corner where the two knife cuts intersect on the front side, so that the corrugated cardboard top paper of the box body 10 is tilted up, and then use your fingers to pick up the tilted corrugated cardboard top paper and tear it off together with the tape. Of course, the knife cut can be cut deeper, so that you can cut into the middle layer of corrugated cardboard. In this way, you can use your fingernail to press the top paper at the angles on the left and right sides of the X-shaped easy tear mark 21, so that there is a certain height difference between the top paper and the angles on the upper and lower sides of the X-shaped easy tear mark 21, making it easier to use your fingernail to scratch the top paper at the knife cut.

[0093] In addition to manually pressing the surface paper at the angles on the left and right sides of the X-shaped easy tear mark 21 with your fingernails, you can also use tools to press the surface paper at the angles on the left and right sides of the X-shaped easy tear mark 21 in advance during production, so as to form a certain gap with the surface paper at the angles on the upper and lower sides of the X-shaped easy tear mark 21. In order to make it easier to remove the surface paper of the corrugated cardboard, you can also use a blade to bevel the surface paper at the upper angle at a smaller angle in the plane direction of the corrugated cardboard. Figure 13 and Figure 14 In this way, the edge of the surface paper of the corrugated cardboard at the upper corner is separated from the middle layer of paper, making it more convenient to use fingernails to pick off the surface paper at the upper corner.

[0094] Since there are two strips of tape sealing the box, tearing off the tape on the front also requires tearing off the tape on the side. Similarly, you can use your fingernails to scratch the surface paper at the angle where the two knife cuts intersect on the side, so that the corrugated cardboard surface paper of the box 10 is tilted up, and then use your fingers to pick up the tilted corrugated cardboard surface paper and tear it off together with the tape. Two grooves can also be provided on the lower side of the two knife cuts along the V-shaped easy-tear mark 21, so that the surface paper forms a certain drop, which is convenient for fingernails to scratch. You can also use a blade to bevel the surface paper at the angle of the V-shaped easy-tear mark 21 at a smaller angle in the plane direction of the corrugated cardboard, as shown in the reference. Figure 13 and Figure 14 In this way, the edge of the surface paper of the corrugated cardboard here is separated from the middle layer of paper, making it easier to pick up the surface paper at the corner with your fingernails.

[0095] Since the easy tear mark 21 is relatively thin, people may not notice the easy tear mark 21. A reminder slogan or reminder mark (not shown in the figure) can be set in the easy tear unit area to make people easily notice that it can be torn.
